Being in a bad mood can lead to illness, because many negative things such as being in a bad mood, paranoid thoughts, worrying too much, negative thoughts, bad hints and bad thoughts can lead to acute illness. Being in a bad mood is really bad for people's health, which may lead to diseases and even life-threatening. The influence of bad emotions on health is not only a speculation, but also a scientific basis. The principle is as follows: First, when we experience strong emotions, our heart rate will increase, our mouth will be dry, our muscles will be tense, even we will tremble, and our faces will change. These are all superficial changes that we can see. Besides, many things have happened under the surface. Physiologically, some strong emotional reactions, such as fear and anger, will activate the body's emergency response system and prepare the body for potential dangers. The sympathetic nervous system is responsible for guiding the adrenal gland to release hormones, which in turn leads to the release of blood sugar from internal tissues, which raises blood pressure and increases sweat and saliva secretion. Second, the body's response to emotions is called stress. Stress reaction includes three stages: alarm reaction, resistance stage and fatigue stage. 1, the alarm response is short-lived, and physiological activation enables the body to act vigorously and get ready. At this stage, the renal epithelial layer will expand, the lymphatic system will be strengthened, and the hormone level will rise, allowing us to respond to stimuli. At the same time, the susceptibility to diseases will also increase. 2. If the stimulation of bad emotions continues, the body will enter a period of resistance. At this stage, the body can endure and resist the stimulation caused by long-term bad emotions. At this stage, the renal epithelial layer contracts, the lymph nodes return to their original state, the original hormone level is stable, and the sensitivity to pressure is improved. If the pressure is kept at a high level, hormones will be exhausted, fatigue will appear, and then enter the third stage. 3. If the bad mood lasts long enough, or the intensity is strong enough, the body's resources will be exhausted and the body will enter a period of exhaustion. At this stage, the lymphatic structure has two possibilities, either enhancement or dysfunction, and the hormone level will increase. At this stage, emotional experience usually leads to depression, which may lead to illness or even death. Being in a bad mood for a long time, the effect of adrenocortical hormone will reduce the ability of phagocytes to kill cancer cells and resist other life-threatening infections. Being in a bad mood for a long time will increase the secretion of emergency hormones, which will damage the integrity of the immune system. Reality has also proved the adverse effects of bad emotions on health. For example, the data prove that African Americans have a higher incidence of heart disease than whites. Studies have proved that the potential cause is not genetic differences, but bad emotions caused by long-term prejudice. African-Americans have a relatively low job status and limited academic qualifications, so it is more troublesome to find a job. Therefore, many people suffer from this frustration for a long time, which in turn affects their mood and leads to a high incidence of heart disease. Facts have proved that bad emotions can really lead to diseases and even life-threatening, so we must control our emotions in time. Therefore, instead of waiting for stress or illness to come to us, it is better to set goals and organize your life healthily. The following suggestions can bring us more happiness and better mental health: 1, never speak ill of yourself; Look for the source of unhappiness and consider what to do next time to have a better effect; Only give yourself and others constructive suggestions-what can you do differently next time to achieve the expected results? 2. Make some good friends to share feelings, happiness and troubles. 3. Cultivate the concept of balancing time and allocate time reasonably to work, society, family, friends and individuals. 4. Always have confidence in your success and happiness, and actively share it with others; Know yourself clearly, know yourself clearly, know your own advantages, and the resources that can be effectively dealt with when facing pressure. When you feel out of control, please leave to avoid unpleasant environment, or put yourself in your shoes, or talk to your sympathizers. 6. Face failure or disappointment bravely. They may tell us that this goal is not suitable for us, or they may let us avoid greater failures in the future in advance. Don't blame yourself for all the failures, it will put too much pressure on us. 7. Cultivate some hobbies, take some time to relax, reflect and enjoy your hobbies, engage in activities that you can be alone, and activities that you can do and enjoy more, so that you can enjoy more pleasure. 8. Grasp the happiness and success of the moment and cherish the moment; At the same time, people have good expectations for the future. What exactly is emotion? We always think that emotion is just some invisible feeling, which is our subjective response to an event. Emotional depression will only affect our mood and won't really hurt ourselves. From a psychological point of view, emotion is not only a psychological state, but also reacts to our physiology and behavior. For example, when we are angry, we may tremble, our scalp may be numb and our behavior is difficult to control. We cry when we are sad, and our flexibility will decrease.

So, where do various emotional signals come from? Not the so-called heart, but our brain. When a stress event begins to enter the brain for processing, our brain will also produce different emotional responses with the characteristics of individual cognitive system. At the same time, the brain, as the processing center of our whole physiological system, will naturally send different signals to the body because of different emotions.

Therefore, negative emotions will definitely have a negative impact on our physiological system, but the intensity is different and the individual reaction is different. Nowadays, people's long-term depression and anxiety caused by various reasons will lead to decreased immunity, dizziness and headache, intestinal diseases, oral ulcers and even other more serious diseases.

In related research, it is found that people who are prone to anger are more related to heart disease; People who are prone to sadness are more prominent in diseases of the immune system; People with more stable emotions and better psychological adaptability have stronger nerve strength, stronger action and more vitality.

Therefore, when we are sick, we often feel sorry for ourselves and complain a lot, which makes negative emotions accumulate. In other words, when we are in a bad mood, because of objective and most subjective reasons, we can't eliminate negative emotions and vent them, we will think that we are very fragile in mental state and body, and our body will also respond to our "expectations".

In daily life, improving one's psychological endurance, enhancing one's reasonable and objective cognitive level, and learning reasonable ways to vent emotions will not only make one's mental health level higher, but also make one's body healthier. Bad mood will inevitably lead to illness. So, first of all, control your emotions. Don't be angry, don't be angry, don't torture yourself. Second, we should be optimistic about books and movies, encourage ourselves, and accept more positive things. Progress is the driving force. There are achievements and progress, even if you are a little scared, you will be happy. My mood will be better. Third, people live in hope. People should have some goals, not too high, and be happy when they achieve them. Step by step, approach the goal every day, be happy every day, and be in a good mood every day. Fourth, emotions are out of control, sometimes out of control, loss of sense of purpose, and serious impulsiveness. Impulse is the devil, it will do something out of line and affect the mood. Fifth, in order to control your emotions, please ask your family and friends to urge you to write a warning on the table to remind yourself. I wish you happiness and progress! If you are in a bad mood for a long time, your quality of life will plummet and your work will be very depressed. Being in a bad mood will affect people's memory, reaction and so on. The most serious point is that being in a bad mood will affect people's endocrine system. For example, patients with depression, especially female patients, will cause a series of problems such as mammary gland hyperplasia, thyroid gland and gynecology. Long-term bad mood will make people's immunity decline. So! Everyone, rich or poor, should come and go happily! Can a bad mood make people sick? The International Health Organization lists reasonable diet, moderate exercise, quitting smoking and alcohol restriction and psychological balance as the four cornerstones of human health. Among them, psychological balance means that people should learn to control their emotions and keep a positive and optimistic state as much as possible, that is, people should have a good mood. Good emotions correspond to bad emotions, including irritability, anger, anxiety, depression and so on, but the core source is anxiety. When studying the factors that affect people's health and lead to various chronic diseases, modern medicine and nutritional medicine find many factors, such as environmental pollution, poor water quality, unsafe food, bad living habits, bad and unreasonable eating habits, emotional anxiety, instability, too little activity, excessive alcohol and tobacco, overwork and so on. These unfavorable factors will produce a chemical called free radicals, which will destroy healthy cells, make them oxidized and become unhealthy. The more free radicals, the more unhealthy cells there will be. When people are in high anxiety and self-blame, the free radicals produced are about half of all other factors. Therefore, being in a bad mood will not only lead to illness, but also be the most critical factor. There is a saying among the people that they have been worried all night. Some cancer patients know that their condition deteriorates rapidly after they have cancer, and many people with sensitive personalities develop faster, which can be explained clearly. Many mental patients, such as obsessive-compulsive disorder, are told by psychological counselors that living with symptoms is actually enduring long-term anxiety, which is not only painful, but also leads to physical problems. Teacher Zeng Qifeng, a psychologist, once said: Now 70% of patients in hospital outpatient departments need to see psychology at the same time. The implication of this sentence is that only when a person has a good mood can he have a good body. For example, a person who has been under pressure for a long time may have no physical problems during physical examination, but he often has inexplicable headaches or gastrointestinal discomfort. A child who has been neglected by his family since childhood may often feel backache when he grows up because he has not been cared for, understood, recognized and tolerated for a long time. During the consultation, I once met such a visitor. She has a bad relationship with her husband and often quarrels and loses her temper and sulks. Later, her upper body was so painful that she couldn't even walk, and even her breathing was terrible. Later, she was hospitalized for a week and found no symptoms. She had to take painkillers, and then she saw Chinese medicine, only to know that long-term anger caused liver depression and qi stagnation, and the collaterals were not smooth, and the pain was so serious. Psychologists have found that people's skin will be flushed and hot when they are excited, and pale and cold when they are nervous or angry. If people's mood changes dramatically, it may also lead to skin allergies and affect hair. Similarly, happy, cheerful and positive emotions can also promote wound healing and make the disease heal. Therefore, body and mind are interrelated, and many times emotions can easily affect people's bodies. Occasionally, a short bad mood is human nature, which will not have much impact on people and will not make people sick. However, long-term persistent bad emotions are harmful to people, which will cause people's resistance to decline, thus inducing diseases; It can also lead to more serious psychological diseases, such as depression and anxiety. Therefore, we should always be alert to our emotional changes and adjust our mentality in time. If you can't adjust for a long time, you need to seek the help of a professional psychologist. Emotion is the response of physiological factors affected by sensory stimulation, which belongs to machinery rather than vanity in a sense. Emotion will directly lead to physiological changes. There are many examples of scientific basis, which is a crisis instinct endowed by nature. Extreme emotions will cause certain adverse consequences to the body, such as cardiovascular and cerebrovascular diseases, lung diseases, liver diseases, skin diseases and so on. Many times it is mild, so it will not be found, but it is a disaster for a long time. Because emotions come from basic cognition, the best way to control emotions is to learn, feel, broaden your knowledge, get to know yourself and the environment as much as possible, abandon too many false feelings of gain and loss, and reach a state of meditation. It may not be easy for most people, but as long as they realize the importance of meditation and are willing to do it, they have already begun to make progress. I am not a physician, and my words are not professional. I hope I can encourage you. Accelerated disease
